2012 Mercedes-Benz C 2.1L Diesel · CA62 CDK

The vehicle presents a concerning maintenance trend that has transitioned from stable to worsening over the last three years. While the 2020 and 2019 tests showed no defects, recent inspections reveal a pattern of recurring mechanical failures and neglected consumable items. The most recent test on 3 June 2026 at 114,291 miles resulted in a pass, but this followed a failure just three miles earlier. That failure highlighted serious issues including a fault in the supplementary restraint system, significant fluid leaks from both front shock absorbers, and an excessively binding offside rear service brake. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 8,164 miles per year. The data shows steady usage without significant gaps, moving from 98,950 miles in November 2020 to the current 114,291 miles in June 2026. This regular usage suggests the vehicle is driven frequently enough to avoid the typical issues associated with long-term standing, yet the increasing frequency of MOT failures indicates that the mechanical upkeep has not kept pace with this regular road use. A prospective buyer must prioritise a thorough inspection of the suspension and braking systems. The record shows a recurring cycle of deterioration in suspension components, specifically with anti-roll bar linkage ball joint dust covers and coil springs being flagged in 2024 and 2025. The shock absorbers have progressed from light misting in May 2025 to serious fluid leaks by June 2026, suggesting the dampers are nearing the end of their service life. Furthermore, the history of binding brakes and corroded brake pipes, noted in 2021 and 2022, warrants a close examination of the calipers and hydraulic lines to ensure no further corrosion or seizing is present. The repeated SRS and ABS warning lamp failures in 2021 and 2026 indicate potential electrical or sensor issues within the safety systems that require professional diagnostic verification. While the recent pass suggests the immediate failures were rectified, the tendency for tyres to be worn close to the legal limit, as seen in both 2021 and 2026, implies a lack of attention to basic consumable maintenance. Any purchase should be contingent on verifying that the recent shock absorber replacements and brake repairs were completed to a high standard.
